To climb Carstensz Pyramid (Puncak Nemangkawi, 4,884 m), you first need to reach Yellow Valley Base Camp (Lembah Kuning), the main base camp and last departure point for the summit, at approx. 4,200–4,300 m. Every itinerary starts and ends in Timika (approx. 30 m). From there, you have two ways in: trekking from Tsinga village, or flying by helicopter directly to base camp.
Both lead to the same summit. The right choice depends on your time, your experience at altitude, and the kind of journey you want.
Trekking access
The trekking route starts at Tsinga village, at approx. 1,400 m, and continues on foot to base camp over several days. We offer two trekking itineraries.
Option A, 11 days. Day 1: arrive in Timika. Day 2: Timika to Tsinga by road. Days 3–5: trek to base camp. Days 6–7: two days reserved for climbing. Days 8–9: trek back to Tsinga. Day 10: back to Timika. Day 11: departure.
Option B, 13 days. Day 1: arrive in Timika. Day 2: Timika to Tsinga by fixed-wing aircraft (Twin Otter). Days 3–6: trek from Tsinga to base camp. Day 7: summit day. Day 8: spare day. Days 9–11: trek back to Tsinga. Day 12: Tsinga to Timika by fixed-wing aircraft. Day 13: departure.
Trekking suits climbers who have more time and want to cover the ground between Tsinga and the high mountains on foot. Gaining height over several days can also help your body adjust, although everyone reacts to altitude differently. Porters are included on trekking packages, but you still need good endurance for multi-day walking, both on the way in and on the way out.
Helicopter access
The helicopter route skips the trek and flies you from Timika straight to Yellow Valley Base Camp. We offer two helicopter itineraries.
Option A, 6 days. Day 1: arrive in Timika. Day 2: helicopter from Timika to Yellow Valley Base Camp. Days 3–4: climbing activities. Day 5: return to Timika. Day 6: departure.
Option B, 8 days. Day 1: arrive in Timika. Day 2: helicopter to base camp. Days 3–4: acclimatization and summit days. Day 5: helicopter back to Timika. Days 6–7: reserve days. Day 8: departure.
Helicopter access suits climbers with limited time, or those who want to focus their energy on the climb itself. The trade-off is altitude: you go from near sea level to more than 4,000 m in a single flight, with no gradual approach. Prior high-altitude experience is especially useful here, and you should discuss the trip with your doctor before you book. Our helicopter packages also list climbing gear (seat harness, helmet, ascending and descending equipment) as included.
Side by side
Time: the trekking itineraries run 11 or 13 days; the helicopter itineraries run 6 or 8 days.
Altitude: trekking gains height over several days from Tsinga (approx. 1,400 m); the helicopter goes straight from Timika (approx. 30 m) to base camp.
Effort: trekking adds several days of walking in and out; the helicopter puts your effort into the climb itself.
What both routes share
Whichever route you choose, some things stay the same. Permits, mountain food, tents and cooking equipment, experienced mountain guides and fixed ropes on the Carstensz wall are part of our packages, with details varying by package. A sleeping bag and personal camping equipment are not included.
Every client must be covered by insurance for cancellation, accident, medical, emergency evacuation, and loss or damage of baggage. The company is not responsible for clients without this cover, and evacuation or rescue costs are not included in our packages.
Weather affects both routes. Our itineraries are guidelines: weather can extend your stay at base camp or delay helicopter and charter flights, so please reserve extra days beyond the planned itinerary. Extra days beyond the agreed itinerary, and costs caused by flight delays or cancellations, are not included.
On both routes, all members go and return as one group. If someone splits from the group, extra costs apply.
Which should you choose?
If you have the time and enjoy long journeys on foot, the trekking route lets you see more of the landscape and gives you more days to adjust to the altitude. If your time is short and you already have experience at high altitude, the helicopter route gets you to the climb quickly. If you are unsure, tell us about your experience and your schedule when you enquire, and we will help you weigh the options.
